Fear is one of the most significant welfare problems in farmed animals, with acute and chronic fear responses causing suffering throughout production cycles across species.
Fear is arguably the most pervasive welfare problem in commercial animal farming. Unlike physical pain which requires specific tissue damage, fear can be triggered by routine management events, unfamiliar stimuli, and chronic environmental stressors that are features of everyday life in intensive production systems. Acute fear during handling and transport causes measurable physiological harm; chronic background fear in poorly managed housing systems suppresses immune function and reduces quality of life continuously. The welfare significance of fear is increasingly recognised in regulatory frameworks and industry codes, but translating this recognition into consistent management practice requires investment in stockperson training and welfare culture change at farm level.
